Adapter rings with AF and exposure are equipped with contacts that transfer all information about the exposure parameters to the camera body. All automatic camera modes will work with them. For newer lenses equipped with an AF engine, it will also work. Older lenses in which the AF drive is transferred by means of a mechanical clutch will work in manual focus mode.
